bolster at different elevations with respect to the base.

Referring now to the drawings, there is shown' at 10 a portion of" the spindle rail of a spinning machine in. which there is seated the Spindle, base in the form of a sleeve 11, thelower portion of which base is threaded at;`12 to receive a lock nut 13 thatholds the base seated firmly down in the rail with its cirrlzumsoribing oil cup 14 firmly upon the ral Disposed within the sleeve 11 is a bolster including the upper cylindrical portion 15 ofmajor external diameter and the lower cylindrical portion .16 of minor external diameter, the former being slidably .fitted within the upper portion ofthe base sleeve.

11,I with `that degree oflooseness common in structures of" this character to permit of ameter, is in material "spaced relation to the wall ofthesleeve,` as illustrated. y

The bolster is supported within the sleeve 111 and against rotation, through the me diumof hanger lugs 17 that radiate from diametrically opposite points of its upper end andwhich lugs are engaged in a pair of notches 185 18 or 18 .in the upper end oi the sleeve.` The. notches of each pair are diametrically opposite and extend downwardly-of the sleeve, the notches 18 having aA slightly `f ryrreater depth than the notches 18 and the notches 18' having slightly greater depth than thenotches 18. Thus, by shiftifngthebol'ster toA engage its lugsl? with the" pairs, of notches interchangeably, the po sition of the, bolster vertically within the sleeve may be adjusted. After positioning the bolster within the` sleeve, a bushing 19 is` screwed into the upper end of the sleeve, which is threaded for that purpose, to position the low end of the bushing in close proximity tothe upper end of the bolster, so thatwhile permitting vibration of the bolster, it will prevent the bolster from rising materially under the` well known influences that tend to that end. To facilitate manipulationot the: retaining bushing, its up- 2l, the spindle blade terminating at its lower end where 1t projects from the bolster, in

the `cone 22a. Y

The point of the cone 22ahas a bearing lon the hard pin 23 that is driven or pressed Y intov an axial perforation 24 in a cap 25 that is internally threaded and engaged upon theV threaded and reduced lower end portion 11 of the tspindle base sleeve 11. Y lt will be understood that by adjustmentoi the cap 25,

this bearing step member 23will be raised or lowered to CorrespondinglyT adjust. the spindle blade 22 or to talreup wear of the lower end of the spindle blade.. The adjusting cap 25 is held in fixed relation to the spindle base through the 'medium ot a Yjam nut 26 that isV engaged upon the threaded portion llof the base above the adjusting` cap.

The oil cup circumscribes thespindle base and is formed integral with it and from the bottom off this oil cup there lead the Vducts27 that are inclined downwardly through the inner wall oli'- the spindle base vsleeve and which register,V respectively `'with ducts 28 that are formed radially through lthe bolster and v open to the bearing surface of the spindle blade. j

With the arrangement of oil cup described,

i itk will be understood that a part of the lubricant supplied, passes by capillary action up# wardly ot the cylindrical portion 22 of the spindle blade while the remainder and greater part gravitates either between the spindle blade and the bolster or between the bolster and base sleeve when initially supplied and when the parts are at rest. When, however, the spindle blade is in rotation, the lubricantes needed, passes upwardly of Y the tapered portion-22 et the spindle blade,

by"` centrifugal action and thus reaches the bearing faces of thezspindle blade and the bolster.

'The whirl employed includes the body .having the bore 31 in its upper end portion that tits upon the spindle blade 22 above the base Vsleeve 11 and below this bore portion 3l is the enlargedchamber 32 in which is received the upper end portion ot thesleeve 11.. The".v lower end portion of the whirl, directly above its lower extremity, is formed with the coaxial drive pulley 33, below which and in spaced relation Vis the radiating cir- 14,hereinbei`ore referred to,

cun'iscribing flange 3l, having its rim turned slightly upwardly, as illustrated, with the resultant channeled upper iiace 35.

llhen a bobbin is raised from the spindle, the tendency is for the whirl and therewith the spindle blade, to rise with it, resulting` in dislocation ol the parts in general and much consequent annoyance. To prevent this, there is associated with the ilange 341-, a pivoted'stop 36 carried at the side oi" the oil cup la and having a hoolr at its upper end that overhangs the channeled Jrace of the flange 34. It the whirl moves upwardly with the bobbin, such movement will be arrested as soon as the flange 34- strikes the bill oi the hook oi the stop member. vlVhen the whirl is to be lifted oli', however, the stop is swung outwardly from its active position, as will be understood.

Itwill be noted that the bore 31 oi the whirl is countersunken at its inner end as shown at 3l and that the upper `end of the bushing 19 enters this countersinl; and that the diametrical slot 2O in the upper end of the bushing, terminates short of the lower end ot the countersink. The bushing is in marked spaced relation to the spindle blade and thus, such lubricant as may pass above the bolster, will be thrown oil centritugally :from the spindle blade and caught within the bushinginstead of passing to the whirl and thence downwardly and linally outwardly from it. A body of oil being thus held about the spindle at the upper end o the bolster, the bearing surface ol the spin dle blade is insured eiiif-ient lulilrication.

lt will be noted that the driving pulley 33 circumscribes the spindle blade between the ends egt the bearing portions between the blade and the bolster. rlhus, the pull laterally oli the driving belt is approximately midway of the ends of the portion et the blade that has its bearing in the bolster, with the evident efficiency ot result.

lllhat is claimed is:

l. The combination with a spindle blade, of a bolster receiving the spindle blade and in which the spindle blade is longitudinali)Y and rotatably movable, a sleeve receiving the bolster and a cap for the lower end of the sleeve adjustably connected therewith and having a bearing for the lower end of the spindle blade, the cap being adjustable with respect to the sleeve longitudinally of it and the spindle blade being adjustable with the cap.

2. The combination with a spindle base sleeve having seats in its upper end, of a bolster movably disposed within the sleeve and having hanger members movably disposed in the seats, a bushing engaged in the sleeve above the bolster and adjustable toward and away from it, a spindle blade having a bearing within the bolster, and a whirl carried by the spindle blade.

3. The combination with a spindle bolster, of a sleeve Within which the bolster is suspended, a spindle blade having a bearing in the bolster and projecting thereabove, a collar surrounding and in spaced relation to the `sndle blade and carried by the sleeve above e bo] ster in close relation to the latter, and a Whirl carried by the spindle and depending around and below the upper end of the collar.

In testimony whereof, I affix my signature, in the presence of a Witness.
